摘要：
Fiber optic surface plasmon resonance sensors based on bi-layers of Ag-TiO2 and Ag-Cu2O are proposed and analyzed experimentally. Influence of oxide layer thickness on the sensitivity of sensors has been discussed. Sensor based on Ag-Cu2O bi-layers has been found to be more sensitive than that of Ag-TiO2 bi-layers. Also, 40 nm Ag-5 nm Cu2O bi-layers based sensor acquires highest sensitivity. Its sensitivity diminishes with rise in thickness of Cu2O layer beyond 5 nm.
